	but even they may have configuration files that it is
	important to back up, lest you need to do all the work to
	configure them all over again.	Another major exception is
	the <TT
CLASS="FILENAME"
>/proc</TT
> filesystem; since that only
	contains data that the kernel always generates automatically,
	it is never a good idea to back it up.	Especially the
	<TT
CLASS="FILENAME"
>/proc/kcore</TT
> file is unnecessary, since it
	is just an image of your current physical memory; it's pretty
	large as well.	</P

	other things in <TT

	you consider important.  </P

> The obvious things to back up are user files
	(<TT
CLASS="FILENAME"
>/home</TT

	(<TT
CLASS="FILENAME"

	all over the filesystem).  </P
